- EEPROM has around a 100000 write cycle. You shouldn't rewrite the
firmware repeatedly and continually; that'll burn the EEPROM
eventually.
## NKRO Doesn't work
-First you have to compile frimware with this build option `NKRO_ENABLE` in **Makefile**.
+First you have to compile firmware with this build option `NKRO_ENABLE` in **Makefile**.
Try `Magic` **N** command(`LShift+RShift+N` by default) when **NKRO** still doesn't work. You can use this command to toggle between **NKRO** and **6KRO** mode temporarily. In some situations **NKRO** doesn't work you need to switch to **6KRO** mode, in particular when you are in BIOS.
-If your firmware built with `BOOTMAGIC_ENABLE` you need to turn its switch on by `BootMagic` **N** command(`Space+N` by default). This setting is stored in EEPROM and keeped over power cycles.

## TrackPoint Needs Reset Circuit (PS/2 Mouse Support)
-Without reset circuit you will have inconsistent reuslt due to improper initialize of the hardware. See circuit schematic of TPM754.

## Can't Read Column of Matrix Beyond 16
Use `1UL<<16` instead of `1<<16` in `read_cols()` in [matrix.h] when your columns goes beyond 16.
-In C `1` means one of [int] type which is [16bit] in case of AVR so you can't shift left more than 15. You will get unexpected zero when you say `1<<16`. You have to use [unsigned long] type with `1UL`.

Properly configure bootloader size in **Makefile**. With wrong section size bootloader won't probably start with **Magic command** and **Boot Magic**.

-Arduino leonardo and micro have **ATMega32U4** and can be used for TMK, though Arduino bootloader may be a problem.

## Using PF4-7 Pins of USB AVR?
-You need to set JTD bit of MCUCR yourself to use PF4-7 as GPIO. Those pins are configured to serve JTAG function by default. MCUs like ATMega*U* or AT90USB* are affeteced with this.

If you are using Teensy this isn't needed. Teensy is shipped with JTAGEN fuse bit unprogrammed to disable the function.
## Problem on BIOS (UEFI)/Resume (Sleep & Wake)/Power Cycles
Some people reported their keyboard stops working on BIOS and/or after resume(power cycles).
-As of now root of its cause is not clear but some build options seem to be related. In Makefile try to disable those options like `CONSOLE_ENABLE`, `NKRO_ENABLE`, `SLEEP_LED_ENABLE` and/or others.
